ABSTRACT:
A collapsible container has a sidewall comprised of a plurality of adjacent raised spirals defining grooves therebetween. Each spiral is comprised of a top side of a first vertical cross section plane length (width) and a shorter bottom side meeting at a fold line. When sufficient force is applied, the bottom side folds inwardly under the upper side, thus collapsing the sidewall and the container.
